T0 all 'wil/0m, it 11mg/ concern.'

Be it known that I, HERMAN C. Pansen, a citizen of the United States,residing at Blue Island, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Draft-Gears, ofwhich the following, taken in connection with the drawings, is adescription.

My invention relates to improvements in draft-gears for railway-cars.

My object is to provide such a draft-gear adapted more especially forcars the sills of which are in a plane above that of the dravbar and ofan improved construction rendering' it particularly strong, durable, andeasy of access for repair when necessary and whereby the travel of thedraw-bar against the resistance of its springs may be reduced to thelowest limit consistent with safety.

In the drawings, Figure 1 is a bottom plan view of my gear with aportion of one side in section. Fig. 2 is a side elevation of the same.Fig. 3 is a detail of the draw-bar yoke. Figs. 4 and 5 are details ofthe castings supporting the compression-springs in the drawbar yoke.Fig. 6 is a modification of the drawbar yoke. Figs. 7 and 8 are detailsof castings used in the yoke shown in Fig. 6. Fig. 9 is a cross-sectiontaken on line 9 9 of Fig. 2 looking in the direction of the arrows. Fig.l0 is a similar view taken on line l() l0 of Fig. 2 looking in thedirection of the arrows. Fig'. l1 is a side elevation of thebody-bolster. Figs. l2, 18, and 14 are details of the castings.

A is the end sill of a car-frame, and B B are the center sills.

C C are the draft-plates, which may be formed of one piece and aresecured in any desired manner to the sills B B.

Angle-irons C' C2 are secured to the sills B B and to the draft-platesC. Two draft-plates C C may be provided, one at each end of the car andeach of a length to abut against or be secured to the body-bolsterDtoward that end of the car, or asingledraft-plate may be provided toextend the full length of the car. The draft-plates C C are secured tothe sills B B by bolts c or otherwise and are notched or recessed, as ata', to receive, lit closely around, and bear against the bod y-bolsterI). By this means the strain upon the bolts c is relieved by the contactof the draft-plate with the body-bolster upon either side thereof, saidbolster receiving the strain coming from either direction. Angle-platesc', Figs. l and l0, are

arranged to lit in the angle formed by the end sill and the center sillsupon each side of the draw-bar, against which the ends of thedraftpla-tes C C abut. This construction not only provides aparticularly strong and durable draftplate, but serves very materiallyto strengthen the underframing of the car.

Angle-plates E are secured to the inner sides of the draft-plates C C,which gives additional strength to the underframing of the car. The endse2 ci of the angle-plates E are bent at the rear end thereof at rightangles. The ends ci of the angle-plates abut against the bumper-blockF3, disposed between them and the body-bolster D.

F is adraw-bar disposed between the draftplates C C and provided at itsstem portion with a yoke F.

Disposed inside of the yoke F and abutting against the end of thedraw-bar Fis a casting or washer f, and abutting against the circularend of this yoke isa similar casting or washer f. Each of these washersf and f' is provided with a projection e c, respectively, hollow uponthe inside and outside and inside of which is disposed the coiledsprings F and f2. Elongated opening's g (/2 are provided in the washersff", respectively, and coincident with these openings g g2 are openingsthrough the draft-plates C, angle-irons C C2, and angle-plates E.Extending loosely through the opening 1/ and coincident openings throughthe draft-plates C, angle-irons Cl C2, and angle-plates E is a forwardbar or follower and extending through the opening g2 and coincidentopenings through the draft-plates, angle-plates, and angle-irons is arear bar or follower H.

I I are tubes provided with forward and rear openings /t vf, coincidentin size and position with the openings g g2. The tubes fit loosely overthe end portions of the bars G H and are held by cotters 7u or the like.In each tube is a cushioning-springII, and around each tube is acushioning-spring' L, the springs bearing at opposite ends,respectively, against the bars Cr H, operating' to press the bar Gragainst the forward ends of the slot g and the bar H against the rearend of the slot g2.

Pressure of the draw-bar in the backward direction causes it to slidethe bar and compress the springs K L against the stationary bar H, whilea pull upon the draw-barcauses it to slide the bar H and compresssprings I( L against the stationary bar Cr. rIhus the same set ofsprings operates against both the forward and rear movement of thedraw-bar and IOO IIO

permits the same to have the limited movement desired.

In Fig. 6 I have shown a modified form of yoke M, which is secured tothe draw-bar F in the same manner as the yoke previously described.Disposed within this yoke NI are the castings m m, Figs. 7 and 8, thecasting m fitting into the circular end of said yoke and the casting mabutting against the drawbar F. The casting m' is practically coneshapedand is provided with an open-ended slot n, through which thefollower-bar G is passed. The rear casting m is provided with a tubularprojection m2, having an open-ended slot n in the end thereof. Thiscasting is also provided with the slotted opening n2, through which thefollower-bar H is passed.

In assembling the parts the. tubular projection m2 is extended into anannular opening m3 in the casting m', Figs. 13 and 14, the slots n and nbeing coincident. The cushioning-springs Fgfz are arranged upon theoutside and inside of the tubular projection m2 and are adapted toresist the strain of the backward movement of the follower-bar Gr andthe forward movement of follower-bar H.

The greatest strain upon the draft-gear in practice takes place usuallyunder the shocks of cars bumping together. The cushioningsprings, whichI have shown disposed inside the yoke and outside the draft-plates,compressing against the follower-bars, take up the strain and shock ofthe cars occasioned by bumping together.

The tubes I I form convenient supports for the springs and maintain themagainst danger of buckling or interference with each other. All parts ofthe draft-rigging' are readily accessible and may be easily and quicklyreplaced in case that repairs are necessary.

As shown and described my improved draftrigging is particularly strong,durable, and well adapted for its purpose; but I do not wish to belimited in details of construction, which may be variouslyT modifiedwithout departing from the spirit of my invention.

The castings which I have shown and described, which are disposed withinthe yoke, might be modified in form and detail to lit any draw-bar yokedesired to be used.
